Given all the stories I’ve been reading at the Consumerist, it wouldn’t surprise me if the airlines still used these things.

Electronic Machine Speeds Fliqht Information to Area Offices

American Airlines has turned to an electronic machine to provide fast, accurate flight information to all its offices in the New York area. The machine, the Magne-tronic Reservisor, is already in use, handling reservations automatically. In its new utilization, information on all flights, incoming and outgoing, is fed into the whirling drum that is the machine’s “memory,”
and is then available at any airline office in the area. To obtain the information, an agent has only to push a simple combination of buttons on the branch-office keyboard. The answer is returned in flashing lights. Immediately available flight information allows the agent to answer queries at once instead of checking bulletin-board postings.
